Quick answer

Mid-term changes credit the unused old plan and charge the remaining new plan period. Wrong-looking amounts usually come from proration mode, invoice status or add-on settings.

Most likely fix: Check settings

How to fix it

Try these in order — the most common fix is first.

  1. 1. Check settings

    1. Settings > Configure Chargebee > Billing LogIQ: confirm Enable Proration
    2. Check proration mode on the invoice, as credits use the mode the invoice was created under
    Did this fix it?

  2. 2. Verify the math

    1. Credit = old price / days in term x unused days
    2. Charge = new price / days in term x remaining days
    3. Example: $30 to $100 on day 15 of 30 = $50 charge minus $15 credit = $35
    Did this fix it?

  3. 3. Adjust

    1. Use a credit note or adjust the invoice
    2. Contact support for item-level proration
    Did this fix it?
